Estudo da fase geométrica adquirida por sistemas físicos quanto- mecânicos, e sua importância no estudo da não-localidade.

Abstract

When a system moves in a cyclical motion from the initial to final state, the wave function acquires a phase. The phase acquired by the physical system, in general, comes from two contributions: one from a dynamic nature and the other from a nature geometric. The geometric phase is not only important for quantum mechanics systems but also for all ondulatory physical. The analysis of a simple one-dimensional mechanical system is used to discuss the relationship between geometric phase and non-classical properties of quantum states. The quantum system investigated in this study is a particle bound to a square well potential, commonly discussed in text-books, except for the possibility that the walls of the well move adiabatically.
